这似乎是一个愚蠢的问题.如何打印if语句？

 private void btnCheckMouseClicked(java.awt.event.MouseEvent evt) {
        String height;
        height = heightCm.getText();
        if ((height >=122) && (height <=188)){
            outputCheck.setText("WORKING...");
        }
    }

新

BigDecimal i = BigDecimal.ZERO;
for (int row = 0; row < testMark.length; row++) {
    for (int col = 0; col < testMark[row].length; col++) {
        i.add(new BigDecimal(testMark[row][col]));
    }
}
i.divide(new BigDecimal(60D));
outPut.setText(i.toString());`

查看代码的底部.我想将整个classAver字符串除以outPut.setText(classAver/60);

数组 double[][] testMark = new double[15][4];

String classAver = "";
        for(int i=0; i < rowNumber; i++){
            classAver += ((testMark[0][0] + testMark[0][1] + testMark[0][2] + testMark[0][3])
                   +
                   (testMark[1][0] + testMark[1][1] + testMark[1][2] + testMark[1][3]) +
                   (testMark[2][0] + testMark[2][1] + testMark[2][2] + testMark[2][3]) +
                   (testMark[3][0] + testMark[3][1] + …
